[0035] Figure 3 Figure 8 is a perspective view of an elevator system 100 that can include an elevator car 103, a counterweight 105, a tension member 107, a guide rail 109, a machine 111, a position reference system 113, and an elevator controller 115. The elevator car 103 is provided, for example, with a car ceiling 101, a car floor 103, a car wall 105, and a car door 107. The elevator car 103 can be configured to move within an elevator hoistway 117 and along the guide rail 109. Figure 4 An example of an elevator car ceiling system is shown and will be described subsequently. The elevator car 103 and the counterweight 105 can be connected to each other by the tension member 107. The tension member 107 can include or be configured as, for example, a steel belt (e.g., a coated steel belt) and / or a rope (e.g., a steel wire rope), among others. The counterweight 105 can be configured to balance the load of the elevator car 103 and can be configured to facilitate movement of the elevator car 103 within the elevator hoistway 117 and along the guide rail 109 in an opposite direction and simultaneously relative to the counterweight 105.

[0036] ​​​​The tension member 107 engages a machine set 111, which can be configured to control movement between the elevator car 103 and the counterweight 105. The machine set 111 can include a motor or similar power device for providing operating power to the elevator system 100, such elevator power devices are often referred to as hoist machines, hoist motors, etc. in practical applications. The position reference system 113 can be mounted on a fixed portion at the top of the elevator hoistway 117, such as on a support pole or guide rail, and can be configured to provide a position signal related to the position of the elevator car 103 within the elevator hoistway 117. The position reference system 113 can be any device or mechanism for monitoring the position of the elevator car and / or counterweight as known in the art, such as but not limited to can be an encoder, sensor, or other system, and can include speed sensing, absolute position sensing, etc.

[0037] The controller 115 can be located in a controller room 121 of the elevator hoistway 117, and can be configured to control operation of the elevator system 100, particularly the elevator car 103. For example, the controller 115 can provide drive signals to the machine set 111 in order to control acceleration, deceleration, leveling, stopping, etc. of the elevator car 103. The controller 115 can also be configured to receive position signals from the position reference system 113 or any other desired position reference device. The elevator car 103 can be stopped at one or more elevator landings 125 as controlled by the controller 115 when moving up or down along the guide rails 109 within the elevator hoistway 117. Although the controller 115 is shown in the controller room 121, it will be appreciated by those skilled in the art that the controller 115 can be located and / or configured elsewhere or in other locations within the elevator system 100, such as can be remotely located or located in the cloud.

[0038] Although shown and described with a roped system including the tension member 107, elevator systems employing other methods and mechanisms for moving an elevator car within an elevator hoistway can equally apply embodiments according to the present disclosure, such as a ropeless elevator system using a self-propelled elevator car (such as equipped with a friction wheel, pinch wheel, or traction wheel), or a ropeless elevator system using a linear motor or hydraulic lift, etc. to move the elevator car. It will be understood that, Figure 3 The illustrated elevator system is a non-limiting example presented for illustrative and explanatory purposes only, and the elevator car and ceiling system disclosed herein can be configured for other lift systems. For simplicity of the drawings, identical or similar parts and features can be designated only at one or several places in the same drawing, the technical terms “first”, “second”, “third”, “fourth”, etc. are only for distinguishing purposes and are not intended to represent their order and relative importance, and the technical term “connected” includes connection in a direct or indirect manner.

[0039] Reference Figure 4As shown, the ceiling system in the elevator car 103 can comprise a ceiling panel 10 and operating means 20, as exemplarily used herein. The ceiling panel 10 is arranged below the car roof of the elevator car 103 and can comprise a first panel 11 and a second panel 12, which can generally be configured to have the same width. Depending on the needs of different applications, one, two or more hinges or the like articulation means 14 can be used to articulate the first panel 11 and the second panel 12 together. In a normal state, the first panel 11 and the second panel 12 can be arranged to be folded on top of each other, for example Figure 4 and Figure 6 unfolded, as shown, so as to be arranged above the interior space 104 of the elevator car 103 by means of them, the ceiling panel 10 can have a masking and decorative effect on the car roof space, such a ceiling panel is often also called a ceiling. If the first panel 11 and the second panel 12 are folded, i.e. the ceiling panel 10 is in a folded state and at least part of the originally covered area is opened, an opening to the car roof can be provided, so that a person or the like can enter the space above to perform various possible operations, such as the corresponding operation of the work platform arranged at the position above the ceiling panel shown in Fig. 1 and Fig. 2, for example, by a worker. Figure 2

[0040] The operating means 20 can be used to implement the state change operation of the ceiling panel 10, i.e. the ceiling panel 10 can be changed from the normal state in which it is normally used to the folded state, or conversely, from the folded state to the normal state. As an example, the operating means 20 can be configured to comprise a roller 21, a roller 22, a roller 23, a roller 24 and a cable 25, as exemplarily used herein.

[0041] In the operating means 20, the roller 21 and the roller 23 can be optionally fixed to one of the first panel 11 and the second panel 12, for example by means of a connection such as a bolt, by any feasible means such as welding, and arranged on opposite sides of the elevator car 103, respectively. For example, in the example shown in Fig. 1 and Fig. 2, the roller 21 and the roller 23 are fixed to the first panel 11 and arranged opposite to each other along the transverse direction (i.e. the width direction) of the elevator car 103. Figure 4 Figure 5 The roller 21 can be rollably arranged on the ceiling frame 15 on the right side of the figure, and the roller 23 can be rollably arranged on the ceiling frame 15 on the left side of the figure, i.e. the ceiling frame 15 corresponding to each of the roller 21 and the roller 23 can serve as a guide limit and support for their rolling movement, and the above ceiling frame 15 is generally fixed to the upper side wall of the elevator car 103. Similarly, the roller 24 can be arranged on the same side as the roller 23 and fixed to the second panel 12, and the roller 24 can roll on the ceiling frame 15 on the side.​​

[0042] For the roller 22, it can be arranged adjacent to the other one of the first and second plates 11, 12, i.e. different from the one to which the rollers 21 and 23 are fixed as discussed above, and the roller 22 can be fixed with respect to the elevator car 103, e.g. by means of any suitable way such as by means of a bolt or the like connector, welding or the like, to the ceiling frame 15 on the same side as the roller 21, in Figure 4 this is schematically shown in

[0043] Generally, the ceiling frame 15 mounted on the upper side wall of the elevator car 103 has a strong rigid structure and is mostly configured in a straight line configuration, whereby both the rollers 21 and 23 can have a feature of a co-linear arrangement, and both the rollers 22 and 24 can have a feature of a co-linear arrangement. With the above arrangement, it will be helpful to achieve the effect of saving time and effort when performing a state change operation of the ceiling plate 10.

[0044] The cable 25 can be used as desired, e.g. a steel wire rope, an alloy material rope, a carbon fiber rope or the like. As shown in Figure 4 and Figure 6 the cable 25 has a first end 25a and a second end 25b, the first end 25a can be fixed to the roller 21, and the second end 25b can be arranged to the inside space 104 of the elevator car 103 after being wound around the roller 22, so as to be provided at a suitable position inside the elevator car 103 for corresponding operation as desired, e.g. by a worker or the like. In this way, one can very conveniently, quickly and efficiently open the opening area to the elevator car without the need to use additional tools such as a ladder, an operating rod or the like, not only saving time and effort when installing and maintaining, but also improving system safety, which is especially beneficial when encountering abnormal or emergency situations of the elevator equipment.

[0045] As an example, as exemplarily used herein, the second end 25b can be optionally fixed to the car operating panel box 30 of the elevator car 103, such as an operating member 31 such as an operating handle can be provided inside the box of the car operating panel box 30, and the second end 25b of the cable 25 can be directly wound and fixed to the operating member 31. In a specific application, e.g. Figure 6As shown, by operating the operating component 31, the cable 25 can be retracted inward or released outward via the second end 25b, thereby changing the current state of the ceiling panel 10 accordingly. For example, during the inward retraction of the cable 25, the ceiling panel 10 can enter a folded state, thus opening the opening above it. The folded panel can then approach or abut against the inner wall of the car. Alternatively, by controlling and maintaining the state of the cable 25, both the first panel 11 and the second panel 12 can be kept extended, keeping the ceiling panel 10 in its normal state. For example, it can be done as follows: Figure 6 As shown, a portion of the cable 25 near the second end 25b is fixed to the operating component 31, so that the cable 25 is normally in a slack or substantially slack state. In this case, the first plate 11 and the second plate 12 can be supported on their respective ceiling frames 15 by rollers, as described above, and thus remain extended. Furthermore, in one or more embodiments, the cable 25 can be kept in a stretched state, allowing the first plate 11 and the second plate 12 to remain extended. This helps to reduce the seam between the first plate 11 and the second plate 12 in the normal state, resulting in a better decorative aesthetic effect.

[0046] As an alternative, in one or more implementations, a motor and control components (such as DIP switches, buttons, etc.) can be installed inside the car control panel box 30. The second end 25b of the cable 25 is connected to the output end of the motor. When needed, the motor can be controlled by operating the aforementioned control components. For example, the motor can be started to rotate forward to retract the cable 25, so that the cable 25 can drive the roller 21 to roll in the direction of the roller 22. At this time, the first plate 11 and the second plate 12 can be induced, for example... Figure 7 and Figure 8 As shown, the ceiling panel 10 folds downwards, thus putting it into a folded state. Figure 7 This illustrates the situation when partial stacking is performed during the above process. Figure 8 This shows the situation when the elevator car is fully or substantially folded up, at which point the opening to the top of the car can be fully or substantially opened, thus providing sufficient space for people to enter the top area of ​​the elevator car.

[0047] It should be understood that the above is merely an example of the present disclosure through specific embodiments. The elevator car ceiling system can have more implementation methods, and thus the elevator car equipped with the ceiling system can also have numerous implementation methods. The elevator car can be of the type of lightweight, high load or low height, and one or more elevator cars according to the present disclosure can be arranged in the elevator system according to the application needs.

[0048] For example, the ceiling panel 10 can be configured as having three or more panel sections, which can be hinged together and, in some cases, can be folded upwards rather than... Figure 6 to Figure 8 The panels fold downwards towards the floor of the elevator car 103 as shown. This can be achieved by attaching hinges to the outer surfaces of these panels facing the floor and / or between two adjacent panels. When the panels of the ceiling panel 10 are folded upwards, the cables 25 can optionally be kept stretched normally, as previously shown. This allows force to be applied to the panels to reduce the seams between adjacent panels in the normal state, resulting in a more satisfactory ceiling finish appearance.

[0049] For example, the panels constituting the ceiling panel 10 can be arranged along the longitudinal direction of the elevator car 103, and / or these panels can have the same or different configurations, such as the same or different widths, or they can be made of the same or different materials, such as stainless steel, aluminum alloy, and / or plastic, or one or more materials. Furthermore, the panels of the ceiling panel 10 can also be moved relative to each other to achieve state transformation, for example, by pulling and moving the first panel above or below the second panel via cables, thereby creating an open opening where the first panel was originally located.

[0050] For another example, while rollers 23 and 24 facilitate the folding operation of the ceiling panel 10, in one or more embodiments, rollers 23 and / or 24 can be removed to simplify the structure, allowing the state-changing operation of the ceiling panel 10 to be performed solely through rollers 21 and 22 and cable 25. In practical applications, the rollers mentioned throughout this document can be in the form of a single roller or multiple rollers.

[0051] The above examples are merely illustrative of the elevator car ceiling system, elevator car, and elevator system according to this disclosure. These examples are for illustrating the principles and implementation methods of this disclosure only and are not intended to limit the scope of this disclosure. Various modifications and improvements can be made by those skilled in the art without departing from the scope of this disclosure. Therefore, all equivalent technical solutions should fall within the scope of this disclosure and be defined by the claims of this disclosure.
